Anker SOLIX C300 vs Anker SOLIX C300 DC
Anker SOLIX C300
Anker SOLIX C300 DCThe C300 DC is 48% lighter, and that is the gap worth deciding on: it is the one you will actually carry. They are level on capacity, rated cycle life and maximum solar input. Scored across this catalogue they land at 4.7 and 5.9 out of 10.

The rows worth your attention are the ones where the gap is large enough to change a decision. On this pair that means weight. Everything else is close enough to ignore.
Where they really separate: weight
This is the one gap large enough to decide the question. The C300 DC comes out 48% ahead on weight, and the reason that matters is practical rather than arithmetic.
There is a threshold between a unit one adult carries upstairs without planning it and one that becomes a two-person job. Cross it and the unit stops moving, which changes what you bought it for.
What each one will run
Same arithmetic for both: usable watt hours after an assumed 85% inverter efficiency, divided by average draw rather than peak.

Common questions
Is the C300 or the C300 DC better value?
This site does not print prices, because a stale price is worse than none. Check both on Amazon, then weigh the gap against the differences above. A 48% lead on weight is worth paying for only if that axis matters to your use.
Can I compare their surge ratings directly?
Not always. BLUETTI's Lifting Power and EcoFlow's X-Boost run appliances above rated output by lowering voltage, which suits a kettle or a heater but not a motor or a computer. A conventional surge rating means something else: a brief tolerance for start-up current. The table keeps each maker's own label attached.
Is the newer one simply a better version?
Not automatically. Makers revise units to hit a different price or size, and a newer model sometimes drops something the older one had. Read the table rather than the generation number.
